The International Union for Conservation of Nature’s (IUCN) Environment and Gender Information (EGI) platform aims—through data and analysis—to convey the value of gender-responsive environmental conservation and sustainable development. By providing new evidence-based information and knowledge products, the EGI platform guides action toward a more just world. Originally launched in its 2013 pilot phase as a composite index, the EGI has evolved into a source for new knowledge creation and dissemination—and for revealing progress and challenges in meeting commitments to women’s empowerment and gender equality in environmental spheres.
